SAMUEL L. MARSH, OF NEW YORK, N. Y.

OIL PURIFIERI Application filed February 9, 1921. Serial No. 443,531.

To all whom it may concern; L Be it known that I, SAMUEL L. MARsH, a citizen of the United States, and residing at New York, N. Y., have invented certain new and useful Improvements in Oil Purifiers, of which the following is a specification.

This invention relatesto the purification or cleansing of oil in its natural state as it .comes from the wells, sumps, tanks, streams or pipe lines and its object is to remove from the oil, its impurities such as water, sand, gas and the like by means of a continuously operating process and apparatus.

-This invention is a continuation of my atent application No. 341,852, filed Decemer 2nd', 1919 which prior application relates broadly to the removal of the sand and water or the like from the oil and toi'specific means for doing it whereas-this invention relates to the addition thereto of means for removing the gas from the oil and to new means and arrangements of means for removing from the purifier, the sand, water, and oil.

'I have shown one embodiment of my invention which is the best of which I amat present informed but it is to be understood'that this is shown in an illustrative sense and not a'limiting one for the invention is capable of a number of different embodiments.

having an inlet l2 curved side walls 13 and 14, an end wall 15, and an inclined bottom 16. The bottom 16 is provided with a false bottom 17 or acentral channel of varying depth, varying from nothing at the upper end to several inches in depth at the outlet 18 from the casing. '19 represents curved ribs on the bottom 16 of the casing leading to the channel 17 and 20 represents curved ribs on the side walls 13 and 14 leading downwardlyto the outlet 18. 21 represents supporting legs for the casing. I

The outlet 18 is provided with a vertical chamber 22, which may be made a part of a siphon or other suction, having an, outlet 23 'whose axial plane is slightly lower than that of the inlet 12. The outlet 23 is connected to a sewer'below the casing or basin The embodiment is illustrated in the accompanying drawings in whichwhereby the suction or siphonic action is produced. At the upper part of the siphon1c or suction chamber 22 is a cleaning plug 24 and at the lower part is a valved exit for removing the sand. This valve is numbered 25 which permits the sand to pass into a sand drum or collector 26 from which the sand may be removed by means of valve 27, when valve 2-5 is closed. 30 represents the top of the casing'll. 31 represents a downwardly inclined deflectorplaced near theinlet '12 and this deflector may be slightly curved. 32and 33 are additional defleccollected or purified oil is adapted to flow I and 38 and 39 represent any suitable means for adjusting the height of'the pipe. The pipe 38 is connectediby piping 40 to a bullhead 41 for collecting an gas which may have escaped from the casing 11 due toany excess pressure therein. 42 is a connection for conveying any gas from thebull-head 41 to the pipe 37 and 43 is an oil outlet from the bull-head.

In operation, the oil in an impure state as I it comes from a well, sump or pipe line,

flows through the inlet 12 under pressure or gravity into the purifier, which is maintained full of liquid up to the dotted line indicating the level thereof. Impact against the deflector 31 causes an oblique change of direction of how of the mixture without emulsification thereof and thereby disturbs the equilibrium of the components of the oil mixture so that the oil particles force their .way upwardly whereas the sand and water pass down the'incline.

This is duplicated but to a lesser degree by each 'of the succeedingdeflectors.

Due to the peculiar construction of the'- false bottom or channel 17 together with the" curved sides 7 13 and 14, the water: flows downwardly at an accelerated speed so that b'y the time the water haspassed the outlet 18 and reached the bottom of chamber 22, it has gathered momentum enough to carry it up and out of the outlet 23 to waste; Thatv is, the depressed channel 17 causes a'flow of water to the Outlet 18 which is accelerated as it descends and this acceleration of the water aided by the impurities directed downwardly by,-the ribs, tendto cause all the liquid impurities to bounce upwardly as it were, after they pass through the outlet 18.and get into the chamber 22. In otherwords, all the sediment or impurities after reaching the bottom of the chamber 22 due to this bouncing, are kept in violent agitation which permitssuction on the outlet 23 to act uponthe impurities to carry the lighter ones over the outlet. The sand or other solid .impurities mixed with the water'being so much heavier, pass out of the bottomof the chamber 22 through the mediumof the valve 25 i and are collected in the tank 26.

The shape of the side walls, plus the shape of thedepressed channel plus the slanting bottom create,-under the u iescent. body of oil, a circular washing tur ulence or eddies .which terminate, or are pulled to, the outlet 18 wherethe velocity of the currents becomes the greatest. This has the effect of agitating, washing and sucking all the'suspended matter (below the quiescent body of oil) out of the liquid, down and through the outlet 18..

p The depressed channel as it increases in depth,.causes an increasing flow of water in it towards the outlet 18 and this'increase of both volume and speed of the water inthe channel in turn causes-a suction toward the outlet 18 wherefit is the strongest. This set-' ting up of 'the washing currents has the result of causing the purification of the oil to" be highly eflective.

As the purlfied-oil accumulates in a qui-i escent' body in the upper part-of the casing, it overflows by either force or gravity through the outlet pipe 38-and the piping 40 to a bull-head and thence to a' reservoir where-it is stored until used. As more or less oil is purified andrises to the top where it remains quiescent irrespective of the downward flowing therebenea'tli, the pipe 38 v .ribs 19. and 20 could be replaced by,;small channels so long as the resulting structure has" the same guiding function as the ribs.

,-,.7. 1. A method of continuously purifying .What I claim is:

petroleum oil which consists of disturbing the ingredients of the impure oil, causing the oil to move upwardly into a relatively quiescent body of purified oil, causin the liquid impurities in the oil to flow own- Wardly below the quiescent body at a uniformly accelerated speed, separating the liquid and the solid impurities, and collecting the gaseous impurities from the oil above the qiiiescent body. p

2. n combination in anoil purifier having oil fiowing continuously 'therethrough,

retarding means for disturbing the equilibrium ofthe oil mixture, channeled and ribbed means forjseparating the liquid and a solidimpurities from the oil andmeans for collecting the gaseous impurities .arising I 7.
